New Revision: 227778

Log:
- When feed-forward clock support is compiled in, change the BPF header to
contain both a regular timestamp obtained from the system clock and the
current feed-forward ffcounter value. This enables new possibilities
including
Is it really necessary to make the ABI dependent on a kernel
configuration option? This causes all sorts of headaches if loadable
modules ever want to use that ABI, something that we just ran into
with vm_page_t and friends and had a long thread on -current about.
Fair question. Julien, if pcap and other consumers will happily ignore
the new ffcount_stamp member in the bpf header, is there any reason to
conditionally add the ffcounter into the header struct?
Cheers,
Lawrence
